IMPROVEMENT IN GUIDES FOR THE STEMS 0F STAMPING-MILLS.

Specification forming part of Letters Patent No. 213,177, dated March11, 1879 application tiled September 21,1878.

To all whom it may concern:

Be it known that we, CHARLES CRANE and WVILLIAM RAUP, of Park'City, inthe county of Summit and Territory of Utah, have invented a newImprovement in Guides` for the Stems of Stamping-Mills, ot' which thefollowing is a specification:

In the. accompanying drawings, Figure 1 represents a front elevation ofour improved battery-guide for stamping-mills. Fig. 2 is a top view ofthe same, partly in horizontal section on line Fig. l, and Fig. 3 is avertical transverse section on line y y, Fig. 2.

Similar letters of reference indicate correspondin g parts.

This invention is intended to furnish an improved battery-guide forstamping-mills of all kinds, by which a strong and solid guide-box forthe stems of the stamps is obtained, and the wooden gibs are readilyremoved from the boxes and replaced. Any guide-box may be repaired whilethe others are in motion, so as to assure economy in time and labor inrepairing, and also in material, as the gibs will last longer andrequire a considerably smaller quantity of wood.

The invention consists of a casting that is attached to the guide-railand battery-posts, and provided with as many semicircular boxsections asthere are stamps in the battery. The stems or rods of the stamps areguided by the iixed semi-boxes, and by detachable box-sections, and byinterior wooden gibs cut with the grain running parallel to the stems.The guide-boxes have removable top caps and bottom flanges for removing`the worn-out gibs and admitting, by metallic washer-sections andset-screws, the adjustment of the gibs to the stems of the stamps.

Referring to the drawings, A represents a casting that runs along theface of the guiderail ot' the battery, and has end anges that are ittedto the battery-posts. 'The casting A is formed with as many semicircularboxsections as there are stamps, and is attached, together with thedetachable front shells or box-sections, B, rigidly, by fastening-boltsa, to the guide-rail of the battery.

The guide-boxes, which are formed by the casting A and shell-sections B,are open at the top, so as to admit the convenient inserting andremoving of the wooden gibs C, but ilanged at the bottom for supportingthe gibs.

The gibs C are out out of the wood in such a manner that the grain runsparallel with the stem of the stamp, so as to avoid their splitting orshaking to pieces, as in the ordinary guides. The gibs can be cut inmore economical manner, as they require a considerably smaller quantityof wood.

The guides-boxes A B are closed at the top by removable caps D, ofsemicircular shape, which are screwed down ou the boxes by setsorews b,for retaining the gibs. By removing the caps the gibs may be readilytaken out at the top and the worn-out gibs replaced by new ones. Thiscan be accomplished at either guide of the battery, and the guidethereby repaired while the remaining stamps are in motion, so as tocontinue thereby the running of the battery, and produce a considerablesaving in time and labor.

The gibs C are moved up close to the stem by means of metallic shells orwashers d, corresponding in shape to the same, and by setscrews e, so-asto make up for the wear of the gibs and give any desired degree of playto the stems, but preventing'their too great Wabbling or vibration.

The gibs last for a considerable length of time, as they wear out butslowly, and hold the stamp as true as possible to the die.

The guides may be. readily repaired, each independently of the other,and are superior to the old guides used in the batteries otlstamping-mills.

Vhat we cla-im as new and of our invention l. As an improvement inbattery-guides, the combination of a continuous casting running alongthe guide-rail, and having semicircular box-sections, with detachablebox-sections, both sections having bottom anges and removable top capsfor the gibs, substantially as and for the purpose set forth.

2. In batteryguides, the combination ot fixed and detachablebox-sections, having bottom flanges and removable top caps, withinterior gibs, adjusted by shell or washer sections and set-screws,substantially as and for the purpose set forth.
